One big problem with non-centralized solar power generating systems is that, while solar panel, inverter and charge controller technology has advanced greatly in the past 20 years, we’re stuck with 100-year-old battery technology. Household deep-cycle batteries are mostly just hugely beefed-up car batteries – they’re enormously heavy, enormously expensive, and have strictly finite lifespans. Unlike everything else in the system, they’re expendable commodities.
This raises a big cost issue with people who have places in the boonies but don’t live there full-time. Their battery costs are as great as those of full-time residents but the expense of new batteries may not be worth it to them.
Which is why, when part-time neighbor TC died, amid the sadness and lost what-if’s an opportunity arose.
TC never got to really develop his property. He had one of those big prefab sheds trucked in, he had a solar power system installed in it, and then he spent two years fighting cancer and I basically never saw him again.
TC died, his son contacted me as caretaker, drove down from out of state to look over the property, and I think he plans to put it up for sale. That could take years, and during those years the solar power components will probably be fine but those already two-year-old batteries will continue to deteriorate.
Meanwhile I have a neighbor whose very expensive battery bank is in the process of giving up the ghost. It must be replaced, but it would cost on the order of $4000 to do a full-on job of it. The property is only used two weekends out of the month tops. Lately, with Monsoon, quite a lot less. A less-expensive alternative would be good.
I’m the caretaker there as well. I won’t cheat either party, but the living are worth more to me than the dead. So I did something I do only very reluctantly: I played middleman. I pointed out the possible opportunity to my neighbor, I explained – but did not overstate – the entropic facts of life to TC’s son. I offered my services as intercessor.
Sums were offered, sums have recently been accepted and will no doubt change hands in due course. And then – oh, my aching back – I’ll be schlepping batteries around. My neighbor got his cheaper alternative, TC’s son got a cash infusion in return for something that he didn’t value and that would otherwise be wasted, and I get goodwill.
Long-time readers know that’s not nothing. I live on goodwill.
